Sample Solution:
Python Code :
Sample Output:
Original DataFrame: company_code date_of_sale sale_amount 0 Abcd 12/05/2002 12348.5 1 EFGF 16/02/1999 233331.2 2 zefsalf 25/09/1998 22.5 3 sdfslew 12/02/2022 2566552.0 4 zekfsdf 15/09/1997 23.0 If a specified column starts with a specified string? company_code ... company_code_starts_with 0 Abcd ... False 1 EFGF ... False 2 zefsalf ... True 3 sdfslew ... False 4 zekfsdf ... True [5 rows x 4 columns]
Pandas Example – Write a Pandas program to filter words from a given series that contain atleast two vowels
Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
